Embodiment 1

[0055] In one embodiment, as figure 1 As shown, the present invention discloses a large data video retrieval method, which specifically includes the following steps:

[0056] S10: Obtain historical surveillance video, and obtain suspicious surveillance video data from historical surveillance data.

[0057] In this embodiment, the historical surveillance video refers to video data acquired by a surveillance device within a certain period of time in the past. Suspicious surveillance video data includes surveillance videos with suspicious behaviors in historical surveillance videos.

[0058] Specifically, the historical surveillance video is obtained from a corresponding big data platform stored in a database storing the historical surveillance video. Wherein, the historical surveillance video can be a public place that actually needs to be monitored, or can be added to the historical surveillance data in the public security system according to the security requirements of the ...

Embodiment 2

[0106] In one embodiment, a big data video retrieval device is provided, and the big data video retrieval device is in one-to-one correspondence with the big data video retrieval method in the above embodiments. Such as Figure 6 As shown, the big data video retrieval device includes a historical video data acquisition module 10 , a suspicious feature extraction module 20 , a behavioral feature extraction module 30 and a retrieval alarm module 40 . The detailed description of each functional module is as follows:

[0107] Historical video data acquisition module 10, used to obtain historical surveillance video, obtain suspicious surveillance video data from historical surveillance data;

[0108] Suspicious feature extraction module 20, is used for extracting suspicious behavior feature and the corresponding behavior identification with suspicious behavior feature from suspicious monitoring video;

[0109] Behavior feature extraction module 30, if obtain video surveillance da...

Embodiment 3

[0128] In one embodiment, a computer device is provided, the computer device may be a server, and its internal structure diagram may be as follows Figure 7 shown. The computer device includes a processor, memory, network interface and database connected by a system bus. Wherein, the processor of the computer device is used to provide calculation and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, computer programs and databases. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The database of the computer equipment is used to store historical monitoring data, suspicious behavior data and behavior identifiers corresponding to the suspicious behavior data. The network interface of the computer device is used to communicate with an external terminal via...

Abstract

The invention relates to the technical field of computer technologies, in particular to a big data video retrieval method and device, computer equipment and a storage medium, and the big data video retrieval method comprises the following steps: S10, obtaining a historical monitoring video, and obtaining suspicious monitoring video data from the historical monitoring data; s20, extracting suspicious behavior characteristics and behavior identifiers corresponding to the suspicious behavior characteristics from the suspicious monitoring video; s30, if the video monitoring data is obtained, extracting personnel behavior characteristics from the video monitoring data; and S40, performing traversal retrieval on the personnel behavior characteristics in the suspicious behavior characteristics, obtaining the behavior identifiers corresponding to the suspicious behavior characteristics which are successfully traversed and retrieved, and generating corresponding alarm information. The method and the device have the effect of obtaining behaviors in the crowd in time.

Description

technical field [0001] The present invention relates to the technical field of computer technology, in particular to a big data video retrieval method, device, computer equipment and storage medium. Background technique [0002] At present, people are paying more and more attention to public security. Most of the public places have installed video surveillance systems, which can monitor public places well and store the video data obtained from monitoring, which is convenient for subsequent review. [0003] In the prior art, the Chinese invention patent with the authorized announcement number CN106339428B discloses a suspect identification method and device based on video big data, including: receiving suspect characteristic information sent by users; Search for the moving target that matches the suspect’s feature information, and extract the feature information corresponding to the moving target; obtain the base station data within the activity range corresponding to the fea...
